I stay at the Mandarin every time I am in Atlanta for business. It has a great location and walking distance to many restaurants.
What I am struck by every time is the level of service from every employee. The valets are polite, professional and gracious. Anyone behind the counter is extremely helpful. If you just stand somewhere in the hotel and look around, many employees will walk up and ask if they can help you. Service from top down is fantastic.
Rooms are great, comfortable and newly renovated. This is one of the few hotels where I sleep well. Bathrooms are well appointed with nice furnishings and wonderful towels.
One of the best features of this hotel is its gym. Plenty of room and lots of machines. It is always very clean with lots of towels and bottled water everywhere.
This is my favorite hotel for business in the U.S. Can't say enough about it.
